An open mind capable of engulfing every source of knowledge without frequent exhaustion is a great way to learn.
  • Holding a good grip and flair knowledge of mathematical skills like problem-solving, data analytics, statistical methods, Regression Analysis, and programming skills like Python, SQL, R, Basic Database knowledge, and SAS are necessary to pursue a data science career. 
  • Learning SQL is a fundamental tool in Data Science as it forms the basic structure in extracting data and exhibiting data analytics. Support Vector Machines, Regression, Clustering are some of the must learn machine learning algorithms a data scientist should know about.
  • Thanks to tons of online platforms, resources, and certifications present, learning the skills is not a mind-boggling task and can be executed by anyone, even a beginner.

Steps involved in entering the Data Science field

For a detailed and staged approach to pursuing a Data Science career, knowing the versatility and making a choice is an important stage.

  • Data scientist, Data Analyst, Marketing Analyst, Business Intelligence Analyst, Machine learning Engineer are some of the many roles involved in choosing a Data Science field.
  •  Choosing the right role in accordance with prior background and experience is a great approach. For beginners, this would be perplexing. Networking with previously worked people and seeking guidance from them regarding the details of each role is a great way to start.

Deep learning of the role and the other aspects it follows.

  • Once you get a clear lucidity of what role you would offer, the next logical step is to completely understand the nature of the role. This doesn’t just include the knowledge of the requirements or the skills the role offers, but also about understanding the scope it has for the future and the complete practicality it brings in applying it.
  • For instance, if you choose to become a Machine Learning Engineer, having knowledge and the prerequisites of the job is necessary. But what makes the difference is when you go a step ahead and have a complete understanding and deeper sense of how it would be applied in reality.
  • Taking a thorough course regarding the role, sticking to the language and the tools required to pursue is a friendly approach to begin.
  • Focusing on problem-solving methods, interpreting solutions, and understanding assumptions, even though the math behind the technique is complex, is a dominant attitude one must have to make groundbreaking progress in this field despite its challenges. 
  • Along with being technically profound, one must not forget the basics of presentation, such as having good communication and networking skills, which always come in handy.
  • Networking with the right people, following the right resources and productive interaction with fellow batchmates is a good approach for beginners.
  • Data Science is a relatively new field, having only a bunch of people decrypting their path. So, finding track of the right guidance and mentorship is an understated knack.
  • The stage of entering a job and having a basic understanding of model deployment is a must.
